Wherein, the heat dissipation unit may be a cooling triangle. The indirect air cooling radiator is characterized in that each radiating unit of the indirect air cooling radiator is provided with a temperature sensor group, the temperature of each radiating unit is measured through each temperature sensor group, so that the data of the temperature field change of each radiating unit of the indirect air cooling radiator can be comprehensively and effectively monitored, and the operating condition of the indirect air cooling radiator can be obtained by analyzing the data and matching the change conditions of meteorological parameters such as air temperature, wind direction and wind speed. Especially for winter operation conditions, effective adjustment means can be adopted according to the change of the monitoring data to prevent the heat dissipation unit from frost cracking, so that intuitive and effective monitoring data are provided for cold-proof and anti-freezing work.
the temperature sensor group can comprise two temperature sensors, and the two temperature sensors are respectively arranged at a first preset position of the first water inlet pipe of the heat dissipation unit and a second preset position of the second water inlet pipe of the heat dissipation unit. The distance from the first preset position to the water inlet end of the first water inlet pipe and the distance from the second preset position to the water inlet end of the second water inlet pipe can be the same or different. Because the positions of the first water inlet pipe and the second water inlet pipe are windward surfaces, and the working environment of the windward surfaces is worst, the actual condition of the wall temperature of the heat dissipation unit can be reflected by temperature data acquired by the temperature sensors arranged on the first water inlet pipe and the second water inlet pipe. In order to avoid introducing additional errors, it may be preferred to set the distance of the first predetermined position from the water inlet end of the first water inlet pipe to the same distance as the distance of the second predetermined position from the water inlet end of the second water inlet pipe, i.e. the first predetermined position is symmetrical to the second predetermined position, taking into account that there may be a certain difference in temperature (equalization and consistency of the temperature field) at different positions from the water inlet end of the water inlet pipe. Therefore, the measured temperature data of the indirect air-cooling radiator is more accurate, and the analysis of the variation trend of the temperature is more facilitated. In addition, in order to facilitate the overhaul and maintenance of workers, preferably, the first preset position and the second preset position are both arranged at a position 2m away from the water inlet ends of the first water inlet pipe and the second water inlet pipe.
